Subaru WRX Concept stuns, but what lies beneath?

15 YRS LATER THE BMW E31 LOOKS FRESH AND FRIGHTENING AS IT DID THE DAY IT ROLLED OFF THE ASSEMBLY LINE. THE 4.0 LITER VARIANT WASN'T BAD BUT SHOULD HAVE BEEN THE 850i WITH THE M70B50 5.0 LITER V12. ESSENTIALLY THE TWO M20 OM;OME SEOXES FISED TPGETJER AT 60 DEGREES/ BUT VERY FEW PARTS FROM THE M20'S CROSS OVER TO THE M70.THE ENGINE REQUIRES INDIBUDULA ECUS FOR EACH CYLINDER BANK AND WEIGHTS IN AT 5322 LBS. STILL A BADASS LOOKING CAR BUT PERFORMANCE WISE IT WAS A BIG DISAPPOINTMENT.
